FEEDING-PAN FOR HUSKERS.

Application filed March 1, 1920.

To all whom it may con corn.

Be it known that I, Josnrn M. Lerner, citizen'of the United States, andresident of Chatfield in the county of Olmsted and Stateof Minnesota,have invented certain new and useful Improvements in Feeding- PansforHuskers, of which the following is a specification. I

This invention relates to feeding pans for corn huskersr One of theobjects of my invention is to provide an automatic feed of corn ears tothe husker mechanism.

Another object of my invention is to provide a device by means of whichcorn ears maysbe fed into a husker in such a way as to permit no morethan one car to be engaged by the husker-knives at one time.

A still further object of my device is to provide means by which aplurality of corn ears may be placed and held in storage for the huskermechanism while new supply is broughtin for the husking operation.

In order to point out the advantages and other objects of my invention,it is in place to explain the prevailing method used at present.

Huskers now in use are either equipped with a complicated and expensivecorn hopper mechanism, or very often lack any provision for retainingand properly discharging corn to the husker feeder.

The latter case is particularly evident in small cheap machines where.it becomes necessary to feed corn ears to the feeding mechanism'by hand,since it would be too costly to install an expensive hopper.

The feeding mechanism usually consists of a plurality of feeding bladesoperating on chain and sprocket principle and adapt-- ed to engageoneear at a time.

The eiiiciency of hand feeding depends entirely upon the skill of theoperator, and when the ears are not placed properly or on time in thepath of the feeding blade, the ears are either cut or otherwiseprevented'from being fed orderly to the husking mechanism.

My invention fills the demand for an inexpensive and simple feed hopperfor corn huskers.

The foregoing and further objects will bemore fully apparent from thefollowing Specification of Letters Patent.

Fig. l is a sectional Referring to the drawings, 10 designates av partof the husker frame com orisin a. table 11 divided through ribs 19.-into oiin partments 13. The ribs extend to the front guard 14- and widenat 15 to hearing lugs '16. lbs upper part of the widened ribs terminateinto inclined partitions 17.

The lugs 16 are adapted to receive a shaft 18 to which are keyedsprocket wheels 19. Each sprocketis driven by link chain 20. l he c1 amconsists of a plurality'of links 21 and so called feeding blades 22which are arranged intermediately between a. certain number of links sothat the kn'ves are equally distanced from each other. These feedingblades, taking the place of a link, travel within the con'ipartments l3and, when reaching the position indicated in dot ted lines at 22, are toconvey one corn car at the time to the hashing mechanism. not shown inthe drawings. i

has been said previously, the ears are ordinarily placed upon the huskertable in front of the inclined partitions 1.7,and, because ofthe rapidmovement of the feeding blades, there is little time left for positioning the ears in correct relation to the feed ing' blades so that theymay be conveyed by the latter in the manner indicated in Fig.1 in dashedand dotted lines at in order to facilitate the proper feeding of theears to the feeding; blades and to enable the operator to store enoughears for the feeding of the husker during his absence, l have provided adevice comprising a stationary member 924i, cut-out at 25 to CO1-respondwhh the compartments 1?) of the 105 husker. Tongues 26 registerwith the widview taken on line ened inclined rib-ends 17 and areattached to them by screws 27 or other convenient means passing throughapertures 28.

Sliding in guides 29provided at the bottom part of pan-member 2d is anadjustable pan-member 30 (see Fig. l), which may be drawn out or broughtin closed position as may be seen in Fig. 3, depending upon the size ofears to be handled.

Riveted or otherwise attached to the upturned sides 31 and 32 of thepan-members are the arms and Set of the adjusting bridge 35, the ends ofwhich are slotted as indicated at 36 and Passing through the slots is abolt 38 provided with washers and a wing-nut for fastening the bridgearms 4 together at any desired position.

Each bridge-arm is provided with a fleaible blade 39 and d0, madepreferably of spring steel and reaching from the bridge in an arc towardtwo of tongues 26. In the drawings are shown but two such blades, and itis self understood that any number of springs may be attached accordingto the design of the husker. 7

As may be seen in Figs. 5, 6 and T, the ends of the bridge-arms areguided.

When the width of the pan is increased, the blade 39 remains stationarywith the bridge-arm 33 of the pan-member 24:, while the blade moves withthe bridge-arm 34: attached to the sliding pan-member 30 until itreaches a position above the last tongue adjacent to the flat end of thestationary pan-member, as may be seen in Fig. 1.

Being fastened to the inclined portion of the rib-extension 17, the rearend il is ele vated and requires a support indicated at 42. T hisconsists of a standard 43, made preferably of piping, with a base orbases id and angular seat 45 to which the pan may be attached if sodesired.

in operation, my device is very simple, nevertheless highly eficienttosaving of time andmaterial and as to properly feeding the huskermechanism.

The pan, once adjusted and fastened to the husker may be permanentlyused for the purpose it isintended.

A number of ears are placed into the pan, preferably, parallel to itsshort sides, although the ears will assume their correct position evenif deposited in disorder, due

to gravity and the arrangement of the flexible blades 39 and d0. 7

the point where the blades come nearest to the tongues 26 the lowest ear45 is held in perfect horizontal position ready to be engaged by thefeeding blades. Between the flexible blades and tongues is room but forone single corn. When the feeding blades reach the position indicated at22 in Fig. 2 and press against the ear, the flexible blades give enoughto permit same to pass out.

Immediately after releasing the lowest ear the spring blades snap-backin their original position, and another ear rolls down between thefiexible blades and tongues by force of gravity.

My primary object is to provide a suitable device for the purpose offeeding corn ears into huskers and I reserve the right to make changesand improvements on same within the scope of my invention, for which 1claim:

1. A feeding pan for corn huskers comprising a stationary member adaptedto be permanently attached to a husker,a movable sliding member, meansfor guiding said sliding member, means for arresting the slidable memberat any desired position in relation to. said stationary member,projecting tongues with intervening open spaces provided at thedelivering end ofsaid stationary member, and spring divides attached tosaid arresting means for holding a corn ear in place prior to itsforcible removal by the husker mechanism.

2. In a feeding pan for huskers, the combination with a stationaryinclined pan member having projecting tongues with intervening openspaces, said open spaces adapted to facilitate the passage therethroughof the feeding blades of the husker, a sliding pan member guided at thebottom of said stationary member, an adjusting bridge connecting saidstationary and said sliding pan members for holding them spaced whendesired, spring guards attached to said bridge for preventing corn earsfrom voluntarily leaving the pan, permitting, however, said ears to beengaged singly by the husker feeding blades and to leave the pan one byone.
